Switzerland – Sewerage work – Wartstrasse, RB Flüeli bis Wülflingerstrasse, KIS

In Wartstrasse, from the Flüeli detention basin (ES 61410) to the relief structure (R6330), there is a 1949-built egg-profile mixed sewer with dimensions 1100/1650 mm. The approximately 1000 m long canal flows through the two storm overflow structures R6130 and R6300. The canal is in poor structural condition and needs to be renovated.
